Toronto Pearson YYZ: the complete layover guide
Two terminals linked by a free train, Priority Pass lounges on nearly every concourse, and a US preclearance setup that moves the American border to Toronto. Here is how to work a Pearson layover.
Layover verdict Good for 3 to 6 hour layovers thanks to broad Priority Pass coverage in both terminals, stressful for tight connections because every transfer involves a queue you do not control.
Best lounge play Plaza Premium runs lounges in T1 and T3 across domestic, international and US departure areas, taking Priority Pass and paid entry, so you can get food and a proper seat in either terminal without status.
The one thing to know US flights clear American immigration in Toronto before boarding. Preclearance runs 3:30 am to 9 pm, and an international to US connection needs 2 hours, not 1.

Orientation
How Pearson is laid out
Pearson is a two terminal airport that behaves like two separate airports. Terminal 1 and Terminal 3 sit a short train ride apart, and there is no airside path between them.
Terminal 1 belongs to Air Canada and its Star Alliance partners. It splits into three zones: D gates for domestic, E gates for international, and the F pier for US departures, which holds the preclearance area and is sealed off airside from the rest of the building. Terminal 3 takes most of the remaining airlines, with B and C gates for domestic and international traffic and Concourse A handling US flights through its own preclearance facility.
The Terminal Link train connects everything landside. It is free, runs 24 hours a day, and stops at Terminal 1, Terminal 3 and Viscount station, where the ALT Hotel sits. Trains come every 4 minutes at peak times and every 8 minutes off peak, and the ride takes 2 to 8 minutes. The train is the easy part. Any terminal change puts you back landside, so after the ride you stand in the full security queue again. Budget 45 to 75 minutes for the whole move, more during morning and evening banks.
Connection honesty: Pearson's reputation for transfer chaos is earned. A same terminal connection on one ticket is usually fine at 90 minutes. An international arrival connecting to a US departure goes straight into the preclearance queue, which can run as long as the regular immigration line, so treat 2 hours as the floor. On separate tickets you start from zero with bags, so give yourself 3 hours.
Getting downtown is genuinely simple. The UP Express leaves from Terminal 1 and reaches Union Station in 28 minutes, with departures every 15 minutes and wifi on board. For a layover run into Toronto, count the full loop at 90 minutes before you have done anything, which makes 6 hours the realistic threshold for leaving the airport. Under that, stay and use a lounge.
Terminal by terminal
What each terminal gives you
Terminal 1
The Air Canada fortress, and the bigger and newer of the two. The lounge depth is real: Maple Leaf Lounges serve the domestic D gates, the international E gates and the transborder F pier, plus a Maple Leaf Express, and the Signature Suite serves Air Canada's top international passengers. Without status, Plaza Premium covers you with an international lounge near gate E77 and a transborder lounge between gates F33 and F55, both reachable with Priority Pass or paid entry when space allows. The walks are long, so do not leave a lounge 20 minutes before boarding and expect a stroll.
Terminal 3
Home to most of the airlines that are not Air Canada. T3 is older and smaller, but it punches above its weight for independent lounge access. The Air France KLM Lounge near gate C32 takes Priority Pass and DragonPass and sells walk in entry at 50 dollars, and Plaza Premium operates here too, including a lounge near gate B24 and a US departures location. The headline feature is the Sheraton Gateway, the only hotel inside the airport, connected to T3 by an indoor walkway. For an overnight layover that is the move.
US preclearance, the Pearson wildcard
Pearson is one of the Canadian airports where US Customs and Border Protection screens passengers before departure, so your flight lands in the United States as a domestic arrival. The facility operates in both terminals from 3:30 am to 9 pm. For origin passengers it is a gift: clear in Toronto, walk straight off the plane in New York or Chicago. Arriving internationally and continuing to the US means you skip Canadian immigration and get routed into the preclearance queue, convenient on paper and slow in practice when several widebodies land together. This is the single biggest reason tight Pearson connections fail, and no lounge strategy fixes it.

FAQ
Pearson layover questions
Can I sleep overnight at Toronto Pearson?
The dependable option is the Sheraton Gateway, the only hotel inside the airport, reached by an indoor walkway from Terminal 3. The ALT Hotel sits at Viscount station on the free Terminal Link train. Whether any free rest zones exist in the terminals is to be confirmed, so plan on a paid bed for a real night.
How do I get between Terminal 1 and Terminal 3 at YYZ?
Take the free Terminal Link train, which runs 24 hours a day; the ride takes 2 to 8 minutes. The train is landside only, so a terminal change means leaving the secure area and clearing security again. Budget 45 to 75 minutes for the full move.
Is wifi free at Toronto Pearson?
Yes. Pearson offers free wifi in both terminals, and it holds up for ordinary browsing and messaging in the gate areas.
What is US preclearance at YYZ and how does it affect connections?
US bound passengers clear American immigration and customs in Toronto, so the flight lands in the US as a domestic arrival. The facility operates in both terminals from 3:30 am to 9 pm. Connecting from an international arrival to a US flight routes you into the preclearance queue, so plan 2 hours for that connection.
Can I leave the airport during a layover at YYZ?
If you meet Canadian entry requirements, yes, and the UP Express puts you at Union Station downtown in 28 minutes with trains every 15 minutes. Entry rules depend on your nationality and may include an eTA or visa; verify before travel. Leave at least 2 hours for the return through security.
Is 1 hour enough to connect at Toronto Pearson?
Only if you stay in the same terminal on a single ticket with an on time inbound, and even then it is uncomfortable. Any connection involving a terminal change or US preclearance makes 60 minutes a genuine gamble. Aim for 2 hours, and 3 on separate tickets.
